Everything has to go to either the white table or an email inbox.
Every other action item that is not in one of those two places needs to be put there.
Don’t get distracted: Handle the first item and don’t put it down until processed!
Make sure you have a filing system, calendar, and places for the “someday” list.
Order the list by priority and indicate context, energy, and time required.
Once per week see what needs to move from one list to another.
Based on your available time, energy, and priority, choose what tasks to do and do them.
There is much more in the book/CD but this is the main process.
